Abstract: A capacitive sensor electrode for sensing a touch input. A material is configured to temporarily modify a capacitance of the capacitive sensor electrode during a period after a touch input has occurred. After the touch input has occurred, a material change in capacitance of the material is relatively slower than an electrode change in capacitance of the capacitive sensor electrode.

Abstract: A single device for emitting and detecting photons. The device comprises a semiconductive layer (3), active material (5), further dielectric layer (17) and overlying electrode (25). In a first mode of operation an electrical field is applied between the semiconductive layer (3) and the overlying electrode (25). This enables photons to be emitted from the active material (5). In a second mode of operation, the semiconductive layer (3) constitutes a channel of a field effect transistor (23). The field effect transistor further comprises source electrode (11), drain electrode (15), gate electrode (13) and dielectric layer (19). Photons absorbed by the active material (5) causes charge to be transferred to the semiconductive layer (3), thereby changing the channel resistance. A plurality of such devices can be arranged in a configurable array.

Abstract: An apparatus comprising: a first layer (512) configured to enable a flow of charge carriers from a source electrode (505) to a drain electrode (506); a second layer (513) configured to generate a voltage in response to a physical stimulus, the second layer (513) positioned so that the generated voltage can affect the conductance of the first layer (512); and a third layer (514) positioned between the first (512) and second (513) layers to prevent a flow of charge carriers therebetween. The third layer (514) comprises a material configured to form electric double-layers (516, 517) at the interfaces with the first (512) and second (513) layers in response to the generated voltage. The formation of the electric double-layers (516, 517) enhances the effect of the generated voltage on the conductance of the first layer (512) such that determination of the conductance of the first layer (512) can be used to allow the magnitude of the physical stimulus to be derived.

Abstract: A photodetector has a two dimensional conductive channel and a quantum dot layer configured to generate charge on exposure to incident electromagnetic radiation. The surface texture of the quantum dot layer has texturing to provide surface roughness which increases the amount of electromagnetic radiation absorbed in the quantum dot layer in comparison to a photodetector having a flat (non-textured) incident electromagnetic radiation surface.
